CB Seal – Compostable and Biodegradable Security Seal
Patented design · The first of its kind in the world · Smart Security with Care for Nature
Key Features
Description
The world's first compostable and biodegradable security seal
CB Seal is a revolutionary solution developed by Lockwise as an ecological alternative to plastic and metal security seals. With more than 30 years of experience in the manufacture and global distribution of security seals, we have created the world's first compostable and biodegradable paper seal, combining maximum security guarantees with a genuine commitment to the environment.
Its unique patented construction makes opening or resealing impossible without leaving visible and irreversible evidence of tampering. The self-adhesive label incorporates perforations and thermochromic ink (heat-sensitive) that detects any removal attempt. At the same time, all its materials—laminated kraft cardboard, natural cotton thread and biodegradable adhesive—are completely compostable and generate no plastic or metal waste.
CB Seal is the ideal choice for companies looking to replace conventional plastic seals in environments where there is no direct exposure to water, aligning their operations with sustainability requirements and the most demanding European environmental regulations.
